Your class is taking a field trip to watch an orchestra perform. The first row of the
concert hall has 20 seats. Each row
thereafter has one more seat in it than
the row before it. If there are a total of 16
rows, what is the seating capacity of the
concert hall

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
